IMPACT OF 0201 COMPONENTS ON CURRENT MANUFACTURING SYSTEMS

The use of 0201 components in consumer products offers a major competitive advantage over other products since they allow significant design miniaturization. This leads to either smaller products or allows more features integrated into the same package size. One of the critical aspects of having the capability of placing 0201 components in any product is the ability of the manufacturing equipment to handle such small components. Many process studies have been completed by manufacturers and equipment suppliers and have shown that tight process windows are required. The current process control for 0402 components is CpK > 1.5 with a 150μm specification window. For 0201 components, the minimum requirement is CpK > 2.0 with a 100μm specification window. The spec window may need to be reduced down to 75μm if the controls for high volume manufacturing are insufficient. Also directly impacting the placement quality is the ability to apply sufficient solder consistently to the board. The goal is to maintain current printing practices, but the effect of powder size will be examined. This paper will evaluate the impact of placement accuracy and solder powder size on 0201 manufacturing quality....
